Agent Ledger
Write-ahead ledger for agent side effects, with an OWASP Agentic Top 10 posture scorer.
Good to know before installing
Records the arguments (up to 4000 chars: terminal commands, file contents, MCP args) and a 300-char result digest of every state-changing tool call in a local plaintext SQLite ledger under HERMES_HOME/plugin-data/agent-ledger/ that is never pruned; injects a warning listing this session's unconfirmed calls into the next turn's context; an optional policy engine (off by default; you add policy.json and set policy_mode) can refuse matching tool calls before they run; the optional posture_daily.py script, run from your own cron, sends a score summary to Telegram with the bot token you give it.
From the plugin's catalog listing.
How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install agent-ledger - Said no? Turn it on later:
hermes plugins enable agent-ledger - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
